What two numbers multiply to -360 and add up to -18?

Here we answer the question: "What two numbers multiply to -360 and add up to -18?"

The answer to your question is:

-30 and 12

Below we illustrate and prove that -30 and 12 multiply to -360 and add up to -18:

-30 × 12 = -360
-30 + 12 = -18

Are you asking because you are trying to figure out how to factor the following quadratic equation?

x² - 18x - 360 = 0

If so, the solution to factor the quadratic equation above is:

(x - 30 ) (x + 12)

To summarize, since -30 and 12 multiply to -360 and add up -18, you know that the following is true:

x² - 18x - 360 = (x - 30 ) (x + 12)
